what is the difference between the jogl classes at dev.java.nt and the jogl classes that have package names like java.gaming...* ???
I’m not exactly sure what you’re asking, but there were essentially two versions of JOGL: the original version in the net.java.games.jogl.* namespace and the current one, the development version of the “official” JSR-231 specification, which is in the javax.media.opengl.* namespace. The latter is the one currently under development; the former is now obsolete. You can download nightly builds of the current source tree from the JOGL home page or find release builds such as JSR-231 beta 5 from the downloads section of the JOGL home page.
